Hanging point, reduces sag, improves elasticity and stability, and road speed is greatly improved.
Dropper is the connection member between carrier cable and contact line in contact net catenary suspension, and its effect is by dropper line
Folder, contact line is hanging on carrier cable, and the length for adjusting dropper is consistent with ensureing that contact line height to the top of rail is tried one's best, with
Improve current carrying quality.
In actual moving process, there is eccentric wear, thimble abrasion, dropper return wire in the dropper of contact net partial sector
The phenomenons such as distortion, branching off etc. in the line of contact net carries out leading adjustment high in special sector.In contact net maintenance maintenance usually
Need often to change dropper, to ensure the elasticity and stability of contact net, for this reason, it may be necessary to designing a kind of dropper changes suspender.
Utility model content
The purpose of this utility model is to provide a kind of dropper to change suspender, and dropper is changed using it, can guarantee that contact
The elasticity and stability of net.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
A kind of dropper changes suspender, it is characterized in that, comprising：
Seamless steel pipe, its two ends have internal thread respectively；
First internal thread cylinder, its one end connects one end of the seamless steel pipe；
Second internal thread cylinder, its one end connects the other end of the seamless steel pipe；
First Full threaded rod, its one end is threadedly coupled the other end of the first internal thread cylinder；
Second Full threaded rod, its one end is threadedly coupled the other end of the second internal thread cylinder；
Four round hooks, its a pair two-by-two, hook is symmetrical is arranged on the another of first Full threaded rod for one pair of which circle
One end both sides, it is another to the symmetrical other end both sides for being arranged on second Full threaded rod of circle hook.
Above-mentioned dropper changes suspender, wherein：
The a length of 400mm of described seamless steel pipe, diameter of phi 10.
Above-mentioned dropper changes suspender, wherein：
First Full threaded rod and the second Full threaded rod 500mm long.
Above-mentioned dropper changes suspender, wherein：
The first described internal thread cylinder and the length of the second internal thread cylinder are 25mm.
Above-mentioned dropper changes suspender, wherein：
The diameter of the round hook described in each is Φ 8, justifies hot bending by light respectively.
Above-mentioned dropper changes suspender, wherein：
Described seamless steel pipe, the first Full threaded rod, the second Full threaded rod are located along the same line.
The utility model has advantages below compared with prior art：It is close to old wire clamp before dropper is changed and installs this work
After dress so that the height of contact net maintains original height, control suspender length is reached by rotating screw thread, realize old dropper
The purpose of stress unloading.
Brief description of the drawings
Fig. 1 is overall structure sectional view of the present utility model.
Specific embodiment
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the utility model is done and is further explained
State.
As shown in figure 1, a kind of dropper changes suspender, it is included：Seamless steel pipe 1, its two ends have internal thread respectively；The
One internal thread cylinder 21, its one end connects the internal thread of one end of the seamless steel pipe 1 by external screw thread；Second internal thread is justified
Cylinder 22, its one end connects the internal thread of the other end of the seamless steel pipe 1 by external screw thread；First Full threaded rod 31, one
The other end of end threaded connection the first internal thread cylinder 21；Second Full threaded rod 32, its one end threaded connection described the
The other end of two internal thread cylinders 22, the accuracy that such whole device is able to lock and height is adjusted by internal and external threads
Within can reaching 5mm；Four round hooks 4, its a pair two-by-two, hook is symmetrical is arranged on the described first full spiral shell for one pair of which circle
The other end both sides of rasp bar 31, it is another to the symmetrical other end both sides for being arranged on second Full threaded rod 32 of circle hook.
Described round hook 4 is U-shaped hook body, and the U-shaped opening phase of the two circle hooks 4 at suspender homonymy two ends is changed positioned at dropper
It is right；In the present embodiment, one end of U-shaped hook body is fixed on corresponding threaded rod as fixing end, and the other end is made as free end
Hook is used, and free end is more long than fixing end, is more beneficial for hooking circuit.
The described a length of 400mm of seamless steel pipe 1, diameter of phi 10.
The Full threaded rod 32 of first Full threaded rod 31 and second 500mm long.
The first described internal thread cylinder 21 and the length of the second internal thread cylinder 22 are 25mm.
The diameter of the round hook 4 described in each is Φ 8, justifies hot bending by light respectively.
Described seamless steel pipe 1, the first Full threaded rod 31, the second Full threaded rod 32 are located along the same line.
Application method of the present utility model is, the present apparatus is close into old wire clamp before dropper is changed and is installed, make upper end and
The round hook of two of lower end hooks the circuit up and down of contact net respectively, the height of contact net is maintained original height, due to seamless
